Dr. Karczmar graduated from Columbia University and University of Medicine and Dentistry of New Jersey. His practice provides comprehensive care for patients with breathing and sleep disorders. His focus encompasses all aspects of pulmonary disorders including, but not limited to asthma, chronic obstructive lung disease (COPD), pulmonary fibrosis/interstitial lung disease, work-related lung disease, chronic cough, and lung cancer. The sleep medicine portion of his practice includes care of patients with insomnia, sleep apnea, narcolepsy, circadian rhythm disorders, and parasomnias (abnormal behaviors during sleep).

Dr. Karczmar is also active on many committees at Coastal Medical and The Miriam Hospital, where he served as the Medical Staff President through 2012. He is also the recipient of several awards for excellence in teaching at the Warren Alpert Medical School of Brown University where he is a Clinical Assistant Professor.

Dr. Karczmar, a native of Warsaw, Poland, has been a Rhode Island resident for more than 25 years. He and his wife, Dr. Cathy Lund (owner of City Kitty Veterinary Care for Cats), and their three cats live in Providence’s historic Elmwood district where they are both active in many community-based organizations including the Institute for the Study and Practice of Non-Violence, Providence Community Library, AIDS Care Ocean State, the Companion Animal Foundation, and City Arts. 

Dr. Karczmar is one of the founding members of Taming Asthma, a non-profit organization that provides free asthma diagnosis, education and treatment for patients without medical insurance. For his work creating this organization, he was the recipient of the 2011 CHEST Foundation Humanitarian Award by the American Academy of Chest Physicians and also was recognized as a Blue Cross/Blue Shield of RI as a Community Hero.

In his spare time, Dr. Karczmar loves to read, travel, argue about RI politics (who doesn’t!), and sail his 45 year-old wooden ketch, Snow Goose.
